Can't get enough of this one.

Some of the lyrics from "The Grand Illusion" by Styx -

So if you think your life is complete confusion because you never win the game.

Just remember that it's a grand illusion. And deep inside we're all the same.
...

So if you think your life is complete confusion because your neighbor's got it made.

Just remember that it's a grand illusion. And deep inside we're all the same.
